This is a column which was erected in the 100's AD. It tells a story of the time and the battles which took place back then. It is right near the center of everything so you can't really miss it, nor should you. On the very top now is a statue of St. Peter. This came later.
Lots of photo ops of this but a little hard to take since it is to tall and you will likely be so close to it to check it out. I used a wide angle lens actually which worked great. It is also fun to photograph this from a little further away so you can see how tall it is and how it fits into the Rome skyline in that part of the City.
Well worth checking out. You can walk by, no charge to see it.
